These guidelines are for larger outboards with planing type hulls, not displacement hulls.
Your reference point is the lowest part of the hull, or keel.
When the anti-ventilation plate is in line with the bottom of the hull, this is Standard.
The engine can be raised 1in. ( 25mm ) above standard for every 10 MPH ( 17km/h ) above 40MPH ( 64km/h )
So if the boat can do over 40MPH ( 64km/h ) the engine can be lifted 1in. If the boat can do 50MPH ( 80.4km/h ) it can be lifted another 1 in. and if possible and the boat can do 60MPH ( 96.5km/h ) the motor can be lifted another 1 in.
So if you have an outboard that can run at 60MPH (96.5km/h ) then your engine should be no less that 3 in. above the lowest part of the boats hull.
But.... For every 12 in. ( 305mm ) the outboard is behind the transom, or a notch in the transom, the engine can be raised 1 in. ( 25mm ) above standard.
The rule in the outboard set up buisness, is that water exiting the bottom of the hull, when on the plane should not be flowing over the top of the anti-ventilation plate, but below it, this reduces drag on the lower unit.
A 150hp Mercury outboard weighs from 390-424 lbs. depending on the model. The Optimax 150 is heavier at 443- 455 bs.
Some have flagella that they rotate as an outboard motor to move around, some have cilia that they use as oars, stroke, return, to move around and some microorganisms just go with the currents in whatever medium they are in.

The mix ratio was probably 20-1 for the older motors due to the older technology oils, in any case the mix using the oil available today will be 50:1. works fine on our old 2 horse.
Electric motors do not produce electricity, they use electricity, and convert that energy to another form of energy, that we measure in horsepower. See related links.
An outboard motor generally is attached either directly to the transom of the boat, or to a bracket that is attached to the transom of the boat.
At the back of the boat. The transom is reinforced to accommodate the boat motor.
On the Yamaha outboard, the model number is located on the port, (left), transom mounting bracket. The transom bracket is the part of the engine that is bolted to your boat transom.
The transom on a boat is the stern on which an outboard motor can be clamped.
A transom plate is a strengthened area used to attach an outboard motor to the rear (or transom) of a boat. see the related links below.
The transom is the stern end of a boat, where you mount the outboard motor on a small boat.
Look for a silver tag on the starboard transom bracket
The "transom" is the back of a boat or ship. For a small boat, an outboard motor might be attached to the transom; for a sailing vessel, the rudder may be attached to the transom. An example sentence might be:"We were on our way back to the dock when a fish jumped over the transom and landed in the boat!"
Should be on the transom bracket facing the motor on starboard side
It depends on the year, but for the most part you will find them on the Starboard side of the engine on the transom bracket (where it connects to the boat.)
At the back of the boat. The transom is reinforced to accommodate the boat motor.
50 hp Force 2-Stroke Outboard Motor. Force 50 hp Outboard is a long shaft. Force 50 hp only weighs 152lbs!! It is one of the lightest 50hp outboards ever made. This is advantageous as it will deliver 50 hp without weighing the transom down.
